I have been using dice a lot in therapy, and playing games with letters to have kids work on their writing, so I wanted to combine the two, and had some other games that use dice, but I wanted to make my own dice with my own stuff on them (more on that later).
I searched Amazon and found these foam cubes that are perfect for adding my own things onto them to use as dice. I put the alphabet and numbers on some, and have put words on other ones. I am currently in love with these foam cubes as I have found many uses for them, and they come in such a large amount that I am not afraid of making mistakes as I can just make another one. I did find an Alphabet Dice on Amazon as well, and may get it, but the foam cubes have come in handy for so many other things.
